Begging for merit should be treated the same as begging for bitcoin and either threads trashed or posts removed, though I suppose in these circumstances the offending begging part could just be edited out by staff. It's only going to get more widespread as people start getting desperate for merit but it's unnecessary as if a post is good then it will naturally receive it. To be honest, I wouldn't even give a post merit regardless of it's 'greatness' if somebody was specifically asking for it.
